Description
本發明總體有關於無線通訊,以及,更具體地,有關於調度通信設備的接收活動。The present invention relates generally to wireless communications, and, more particularly, to scheduling reception activities of a communications device.
術語「無線」通常是指電氣或電子操作,無需使用「硬接線」連接即可完成。「無線通訊」是在不使用電導體或電線的情況下遠距離傳輸資訊。所涉及的距離可能很短(電視遙控器為幾米)或很長(無線電通信為數千甚至數百萬公里)。無線通訊最著名的例子是蜂窩電話。蜂窩電話使用無線電波使操作員能夠從世界各地的許多地方向另一方打電話。它們可以在任何地方使用,只要有一個蜂窩電話網站來容納可以發送和接收信號的設備,這些信號經過處理可以在蜂窩電話之間傳輸語音和資料。The term "wireless" generally refers to electrical or electronic operations that can be accomplished without the use of "hardwired" connections. "Wireless communication" is the transmission of information over long distances without the use of electrical conductors or wires. The distances involved may be short (a few meters for a television remote control) or long (thousands or even millions of kilometers for radio communications). The most famous example of wireless communication is the cellular phone. Cellular phones use radio waves to enable operators to call another party from many locations around the world. They can be used anywhere as long as there is a cellular phone site to house a device that can send and receive signals that are processed to carry voice and data between cell phones.
在無線通訊裝置的開發中,省電一直是一個重要的問題。隨著蜂窩電話(或移動台)或任何無線通訊裝置的功能變得越來越強大,無線通訊裝置的耗電速度也越來越快。可在無線通訊系統中利用各種技術來説明無線通訊裝置省電。例如,可採用非連續接收(discontinuous reception,DRX),以允許無線通訊裝置在一段時間內無需監測控制通道。因此,無線通訊裝置可在一段時間內處於 DRX 模式(例如睡眠),並在另一時間段內處於活動模式(例如喚醒、監測控制通道等),用於監測控制通道的功耗可相應減少。In the development of wireless communication devices, power saving has always been an important issue. As cellular phones (or mobile stations) or any wireless communication device becomes more and more powerful, the wireless communication device consumes power faster and faster. Various techniques can be utilized in wireless communication systems to achieve power saving in wireless communication devices. For example, discontinuous reception (DRX) can be used to allow the wireless communication device to not need to monitor the control channel for a period of time. Therefore, the wireless communication device can be in DRX mode (e.g., sleep) for a period of time and be in active mode (e.g., wake up, monitoring control channel, etc.) for another period of time, and the power consumption used to monitor the control channel can be reduced accordingly.
然而,若在一段時間內放棄對控制通道的監測,通信品質可能會下降。因此,非常需要一種用於調度通信設備的接收活動的智慧方法,可在保持通信品質的同時降低功耗。However, if monitoring of the control channel is abandoned for a period of time, communication quality may degrade. Therefore, there is a great need for a smart method for scheduling reception activities of communication devices that can reduce power consumption while maintaining communication quality.

第3圖是UE(如通信設備100)處於RRC連接狀態的DRX配置的示範性示意圖。舉例來說,網路裝置可通過無線電資源控制(radio resource control,RRC)信令配置DRX週期的長度,以及UE的DRX開啟期間(DRX ON duration)或DRX關閉期間(DRX OFF duration)。UE需要在DRX開啟期間監測物理下行鏈路控制通道(physical downlink control channel,PDCCH),而無需在DRX關閉期間監測PDCCH或執行發送或接收活動。有時UE可在DRX關閉期間進入睡眠模式以省電。Figure 3 is an exemplary schematic diagram of a DRX configuration in which a UE (such as the communication device 100) is in an RRC connected state. For example, the network device can configure the length of the DRX cycle and the UE's DRX ON duration or DRX OFF duration through radio resource control (RRC) signaling. The UE needs to monitor the physical downlink control channel (PDCCH) during DRX on, but does not need to monitor the PDCCH or perform sending or receiving activities during DRX off. Sometimes the UE can enter sleep mode during DRX off to save power.
然而,由於各種測量需求,傳統UE仍需在DRX關閉期間醒來以執行一些測量,如測量一個或多個參考信號(reference signal,RS),而這些測量確實會造成UE的額外功耗。為了解決這個問題,提出了調度通信設備的接收活動以降低功耗但仍能保持通信品質的方法。However, due to various measurement requirements, traditional UEs still need to wake up during DRX shutdown to perform some measurements, such as measuring one or more reference signals (RS), and these measurements do cause additional power consumption of the UE. To solve this problem, methods have been proposed to schedule reception activities of communication devices to reduce power consumption but still maintain communication quality.
第4圖是根據本發明實施例的調度通信設備接收活動的方法流程圖,用於通信設備以更省電的方式從無線網路的網路裝置接收無線電信號。上述方法可包括以下操作或步驟,可由數據機處理器222執行。Figure 4 is a flow chart of a method for scheduling reception activities of a communication device according to an embodiment of the present invention, which is used for the communication device to receive radio signals from a network device of a wireless network in a more power-saving manner. The above method may include the following operations or steps, which may be executed by the

步驟S406:根據通信設備的場景確定一個或多個接收相關參數。Step S406: Determine one or more reception-related parameters according to the scenario of the communication device.
步驟S408:根據一個或多個接收相關參數在至少一個DRX關閉期間調度一個或多個接收活動。Step S408: Schedule one or more reception activities during at least one DRX shutdown period according to one or more reception related parameters.
根據本發明一實施例,當數據機222根據步驟S406中確定的一個或多個接收相關參數在至少一個DRX關閉期間調度一個或多個接收活動以接收RS時,可產生最終RS調度樣式並提供給無線電收發器110,以執行一個或多個所調度的接收活動,從而基於最終RS調度樣式在相應時間接收相應RS。數據機處理器222可隨後在所接收RS上執行相應測量。According to an embodiment of the present invention, when the
根據本發明的實施例,數據機處理器222可重複執行第4圖中的操作或步驟。也就是說,數據機處理器222可重複執行步驟S402以收集最新資訊用於後續參數確定以及接收活動調度。若最新收集的資訊指示出通信品質或性能的下降,則意味著先前參數確定和接收調度可能已不再合適。數據機處理器222可基於最新收集的資訊和相應場景,在步驟S406中調整接收相關參數,並在步驟S408中調度接收活動。如此一來,接收相關參數和接收活動的調度可基於最新收集的資訊即時動態或適應性調整。According to embodiments of the present invention, the
根據本發明的實施例,可基於通信設備100的至少一參數收集有關網路和通信設備的操作的資訊。上述至少一參數可為以下參數中的至少一個:輸送量(如上行鏈路以及/或者下行鏈路流量負載)、姿勢、加速器輸出、調製編碼方案(modulation and coding scheme,MCS)、塊錯誤率(block error rate,BLER)、信噪比(signal to noise ratio,SNR)以及互資訊(mutual information)。According to embodiments of the present invention, information about the operation of the network and the communication device may be collected based on at least one parameter of the
在本發明的實施例中,輸送量或者上行鏈路以及/或者下行鏈路流量負載可由數據機處理器222以及/或者應用處理器130監測或計算。當數據機處理器222以及應用處理器130均監測或計算輸送量或流量負載時,統計結果可進行平均或者加權後組合以獲得最終統計結果。In embodiments of the present invention, throughput or uplink and/or downlink traffic load may be monitored or calculated by the

在本發明的實施例中,數據機處理器222可計算所測量參考信號的SNR。舉例來說,數據機處理器222可計算追蹤參考信號(tracking reference signal,TRS)、同步信號/物理廣播通道(physical broadcast channel,PBCH)塊(SSB)、通道狀態資訊參考信號(channel state information reference signal,CSI-RS)、PDCCH解調參考信號(demodulation reference signal,DMRS)、PDSCH DMRS等。In embodiments of the present invention, the
在本發明的實施例中,互資訊可為指示信號品質的指示符,並可在數據機處理器222執行通道估計和PDSCH解碼時獲取。In embodiments of the present invention, the mutual information may be an indicator of signal quality and may be obtained when the
在本發明的實施例中,所收集的有關網路和通信設備的操作的資訊可包括RRC配置資訊。在一示範例中,數據機處理器222可從RRC配置資訊中獲取DRX週期的週期、DRX週期的開啟/關閉期間的長度、DRX週期的開啟/關閉期間的位置、DRX相關計時器的設定,以及參考信號的位置和匹配值。In embodiments of the present invention, the collected information about the operation of the network and communication devices may include RRC configuration information. In an example, the
根據本發明的實施例,一個或多個接收相關參數可包括週期靜音指示符Cycle_Muting_Ind,指示非靜音DRX週期的數目與所配置DRX週期的數目之比。在本發明的實施例中,當在步驟S408調度一個或多個接收活動時,數據機處理器222可在非靜音DRX週期的DRX關閉期間調度一個或多個接收活動。舉例來說,當週期靜音指示符Cycle_Muting_Ind被設定為1:4時,意味著4個所配置DRX週期中有1個非靜音DRX週期。換句話說,在4個連續DRX週期中,有3個靜音DRX週期和1個非靜音DRX週期。According to an embodiment of the present invention, the one or more reception related parameters may include a cycle muting indicator Cycle_Muting_Ind indicating a ratio of the number of non-muting DRX cycles to the number of configured DRX cycles. In embodiments of the present invention, when one or more reception activities are scheduled in step S408, the
請注意,在本發明的一些實施例中,週期靜音指示符Cycle_Muting_Ind也可視為或轉化為下取樣速率。在一示範例中,當週期靜音指示符Cycle_Muting_Ind被設定為1:4時,下取樣速率為4。也就是說,在4個所配置DRX週期中,只有1個DRX週期在其DRX關閉期間是非靜音的,剩下3個DRX週期將被靜音(即DRX關閉期間不會安排接收活動)。因此,與所有DRX週期的DRX關閉期間均為非靜音並可安排接收活動(例如用於相鄰社區測量或通道估計的接收活動)的傳統方法相比,基於本發明的方法,非靜音DRX週期(即DRX關閉期間不能睡眠,仍需醒來執行接收活動用於RS測量的DRX週期)的下取樣速率從1(即無下採樣)提高到4。Please note that in some embodiments of the present invention, the cycle muting indicator Cycle_Muting_Ind can also be regarded or converted into a downsampling rate. In an example, when the cycle muting indicator Cycle_Muting_Ind is set to 1:4, the down-sampling rate is 4. That is to say, among the 4 configured DRX cycles, only 1 DRX cycle is non-muted during its DRX off period, and the remaining 3 DRX cycles will be muted (that is, no reception activities will be scheduled during the DRX off period). Therefore, compared with the traditional method in which the DRX off period of all DRX cycles is non-silent and reception activities (such as reception activities for neighboring community measurements or channel estimation) can be scheduled, based on the method of the present invention, the non-silent DRX cycle (i.e., you cannot sleep during DRX off period, you still need to wake up to perform receiving activities for the DRX cycle of RS measurement). The down-sampling rate is increased from 1 (i.e., no down-sampling) to 4.
根據本發明的實施例,一個或多個接收相關參數可進一步包括參考信號靜音指示符RS_Muting_Ind,指示哪個參考信號的接收活動將在非靜音DRX週期的DRX關閉期間調度。請注意,參考信號靜音指示符RS_Muting_Ind也可指示哪個參考信號的接收活動不在非靜音DRX週期的DRX關閉期間調度(即靜音)。According to an embodiment of the present invention, the one or more reception related parameters may further include a reference signal muting indicator RS_Muting_Ind, indicating which reference signal reception activity will be scheduled during the DRX off period of the non-muting DRX cycle. Note that the reference signal muting indicator RS_Muting_Ind may also indicate which reference signal whose reception activity is not scheduled (i.e. muted) during the DRX off period of the non-muting DRX cycle.
在一示範例中,參考信號靜音指示符RS_Muting_Ind可指示SSB和TRS的接收活動均將在一個或多個後續非靜音DRX週期的DRX關閉期間調度,以用於SSB測量和TRS測量;或者僅SSB的接收活動將在一個或多個後續非靜音DRX週期的DRX關閉期間調度(TRS的接收活動將在一個或多個後續非靜音DRX週期中靜音),以用於SSB測量;或者僅TRS的接收活動將在一個或多個後續非靜音DRX週期的DRX關閉期間調度(SSB的接收活動將在一個或多個後續非靜音DRX週期中靜音),以用於TRS測量等。In an example, the reference signal muting indicator RS_Muting_Ind may indicate that reception activities of both SSB and TRS will be scheduled during the DRX off period of one or more subsequent non-muting DRX cycles for SSB measurements and TRS measurements; or only SSB The receive activity will be scheduled during DRX off for one or more subsequent non-silent DRX cycles (the receive activity for TRS will be muted for one or more subsequent non-silent DRX cycles) for SSB measurements; or the reception of TRS only Activity will be scheduled during DRX off for one or more subsequent non-silent DRX cycles (SSB's receive activity will be muted for one or more subsequent non-silent DRX cycles) for TRS measurements etc.
根據本發明的實施例,一個或多個接收相關參數進一步包括參考信號視窗指示符RS_Win_Ind,指示選擇待調度參考信號的哪個接收視窗來調度參考信號的接收活動。一般來說,網路裝置可多次發送參考信號,從而為每個參考信號創建多個接收視窗。後續非靜音DRX週期中有多個接收視窗用於接收預定參考信號時,數據機處理器222可選擇最接近於DRX開啟期間的位置,或選擇與DRX開啟期間全部或部分重疊的位置,以進一步降低功耗。According to an embodiment of the present invention, the one or more reception related parameters further include a reference signal window indicator RS_Win_Ind, indicating which reception window of the reference signal to be scheduled is selected to schedule the reception activity of the reference signal. Generally speaking, a network device can send a reference signal multiple times, thereby creating multiple reception windows for each reference signal. When there are multiple reception windows for receiving the predetermined reference signal in the subsequent non-silent DRX cycle, the
根據本發明的實施例,數據機處理器222可在兩階段中確定通信設備100的場景,以從多個方面考慮通信設備100的狀態。在場景確定的第一階段中,數據機處理器222可確定通信設備100的運動狀態。在場景確定的第二階段中,數據機處理器222可確定通信設備100的流量負載。According to embodiments of the present invention, the
此外,為了回應於兩階段分別確定的場景,數據機處理器222可基於場景確定的第一階段中確定的通信設備100的運動狀態,確定第一週期靜音指示符;並可基於場景確定的第二階段中確定的通信設備100的流量負載,確定第二週期靜音指示符;以及根據第一週期靜音指示符和第二週期靜音指示符確定最終週期靜音指示符。In addition, in response to the scenarios determined in the two phases respectively, the
在本發明的實施例中,數據機處理器222可直接將嚴格的那個作為最終週期靜音指示符。在一示範例中,若第一週期靜音指示符確定為1:4,第二週期靜音指示符確定為1:8,則數據機處理器222可直接將嚴格的那個(如具有更小下取樣速率的第一週期靜音指示符)作為最終週期靜音指示符。In an embodiment of the present invention, the
第5圖是根據本發明實施例的步驟S404和S406中場景和參數確定的更細節操作的流程圖。本方法可包括數據機處理器222執行的下述操作或步驟。Figure 5 is a flow chart of more detailed operations of scene and parameter determination in steps S404 and S406 according to an embodiment of the present invention. The method may include the following operations or steps performed by the
步驟S502:在場景確定的第一階段中確定通信設備100的運動狀態,並基於所確定的運動狀態確定第一週期靜音指示符。根據本發明的實施例,數據機處理器222可基於姿勢、加速器輸出,或者姿勢感測器、位置感測器以及/或者活動感測器的檢測或感知結果,確定運動狀態。在本發明的實施例中,運動狀態可包括旋轉、移動、非靜態和靜態(或准靜態),當然本發明並不限於此。根據本發明的實施例,當確定通信設備100處於旋轉或移動狀態時,非靜音DRX週期的下取樣速率可設定為更小的值。也就是說,對於旋轉或移動狀態來說,通信設備100優選更頻繁地執行測量,靜音DRX週期的數目優選更少。舉例來說,旋轉或移動狀態的第一週期靜音指示符可被設定為1:2、1:3等。相反,對於靜態或准靜態的狀態來說,通信設備100可不那麼頻繁地執行測量,以降低額外功耗,因此非靜音DRX週期的下取樣速率可設定為更高的值。舉例來說,靜態或准靜態狀態的第一週期靜音指示符可被設定為1:8、1:10等。Step S502: Determine the motion state of the
步驟S504:在場景確定的第二階段中確定通信設備100的流量負載,並基於所確定的流量負載確定第二週期靜音指示符。根據本發明的實施例,數據機處理器222可基於上行鏈路以及/或者下行鏈路負載、輸送量、MCS、上行鏈路以及/或者下行鏈路調度資訊等確定流量負載。數據機處理器222可利用一個或多個閾值來確定通信設備100的流量負載較輕、中等或過重。對於輕負載場景來說,非靜音DRX週期的下取樣速率可被設定為較高的值,例如第二週期靜音指示符可被設定為1:8、1:10等。對於中等負載場景來說,非靜音DRX週期的下取樣速率可被設定為較低的值,例如第二週期靜音指示符可被設定為1:2、1:3等。對於重負載場景來說,對非靜音DRX週期進行下採樣來降低額外功耗的操作可停止,第二週期靜音指示符可被設定為1:1。Step S504: Determine the traffic load of the
請注意在本發明的實施例中,每個運動狀態和每個流量負載場景的最高下取樣速率(或週期靜音指示符閾值)可預先確定。數據機處理器222可確定不高於步驟S502和S504中相應最高下取樣速率的相應週期靜音指示符。Note that in embodiments of the present invention, the maximum downsampling rate (or periodic silence indicator threshold) for each motion state and each traffic load scenario may be predetermined. The
步驟S506:根據第一週期靜音指示符和第二週期靜音指示符確定最終週期靜音指示符。在本發明的實施例中,數據機處理器222可直接將最嚴格的那個作為最終週期靜音指示符。舉例來說,若第一週期靜音指示符被確定為1:8,而第二週期靜音指示符被確定為1:2,則最終週期靜音指示符可被設定為1:2。請注意在本發明的一些實施例中,數據機處理器222也可綜合考慮有關網路和通信設備的操作的資訊(例如SNR、BLER、MI、MCS等)來確定最終週期靜音指示符。舉例來說,SNR或MI越高,以及/或者BLER越低,可選擇越高的下取樣速率。Step S506: Determine the final periodic silence indicator based on the first periodic silence indicator and the second periodic silence indicator. In an embodiment of the present invention, the
步驟S508:確定通信設備100是否將要操作在低功率模式以降低額外功耗。若最終週期靜音指示符被設定為1:1,則確定通信設備並不會操作在低功率模式,隨後將進行步驟S514。若最終週期靜音指示符未被設定為1:1,則確定通信設備將操作在低功率模式,隨後將進行步驟S510。Step S508: Determine whether the
步驟S510:根據步驟S506中確定的最終週期靜音指示符,並綜合考慮有關網路和通信設備的操作的資訊(例如SNR、BLER、MI、MCS等),來確定參考信號靜音指示符RS_Muting_Ind。SNR或MI越高,以及/或者BLER越低,可靜音更多的接收活動以及/或者更多的參考信號(也就是說,將不會在非靜音DRX週期的DRX關閉期間調度)。在一示範例中,數據機處理器222可選擇具有更高SNR的參考信號在非靜音DRX週期的DRX關閉週期調度。在另一示範例中,數據機處理器222可選擇至少一接收視窗落入非靜音DRX週期的DRX關閉期間內的參考信號作為待調度參考信號。在另一示範例中,當有關網路和通信設備的操作的資訊顯示通信品質或性能差於預定閾值時,數據機處理器222可確定沒有參考信號在非靜音DRX週期的DRX關閉期間靜音。Step S510: Determine the reference signal muting indicator RS_Muting_Ind according to the final periodic muting indicator determined in step S506 and comprehensively considering information about the operation of the network and communication equipment (such as SNR, BLER, MI, MCS, etc.). The higher the SNR or MI, and/or the lower the BLER, the more receive activity and/or the more reference signals that can be muted (that is, will not be scheduled during the DRX off period of the non-muted DRX cycle). In an example, the
步驟S512:根據步驟S506中確定的最終週期靜音指示符,並綜合考慮有關網路和通信設備的操作的資訊(例如SNR、BLER、MI、MCS等),來確定參考信號視窗指示符RS_Win_Ind。如先前所述,數據機處理器222可選擇最接近於DRX開啟期間位置的接收視窗,或者選擇全部或部分重疊於DRX開啟期間的接收視窗,以降低功耗。Step S512: Determine the reference signal window indicator RS_Win_Ind according to the final periodic silence indicator determined in step S506 and comprehensively considering information about the operation of the network and communication equipment (such as SNR, BLER, MI, MCS, etc.). As mentioned previously, the
步驟S514:確定不執行RS靜音。也就是說,當最終週期靜音指示符被設定為1:1時,沒有靜音DRX週期,數據機處理器222可調度需在DRX週期的DRX關閉期間中監測的所有參考信號的接收活動。Step S514: Determine not to perform RS muting. That is, when the final cycle mute indicator is set to 1:1, there is no mute DRX cycle, and the
如先前所述,可基於最新收集的資訊即時動態或適應性調整一個或多個接收活動的接收相關參數和調度。舉例來說,當最新收集的資訊(如降低的SNR或增長的BLER)顯示通信品質或性能的降低時,數據機處理器222可降低下取樣速率以及/或者確定不執行RS靜音,以更頻繁執行測量。相反,當最新收集的資訊(如增長的SNR或降低的BLER)顯示通信品質或性能的改進時,數據機處理器222可降低下取樣速率以及/或者確定不執行RS靜音,以較不頻繁地執行測量,從而在DRX關閉期間降低額外功耗。As mentioned previously, reception-related parameters and scheduling of one or more reception activities can be adjusted dynamically or adaptively based on the latest collected information. For example, when newly collected information (such as reduced SNR or increased BLER) indicates a degradation in communication quality or performance, the
第6圖是根據本發明實施例的週期靜音指示符Cycle_Muting_Ind被設定為1:4時最終RS調度樣式的系統示意圖。在本實施例中,前3個DRX週期的DRX關閉期間沒有額外功耗。與下取樣速率為1(即無下採樣)的傳統方案相比,本實施例中的總體功耗可大幅降低至1/4。Figure 6 is a system diagram of the final RS scheduling pattern when the cycle muting indicator Cycle_Muting_Ind is set to 1:4 according to an embodiment of the present invention. In this embodiment, there is no additional power consumption during the DRX off period of the first 3 DRX cycles. Compared with the traditional solution with a downsampling rate of 1 (that is, no downsampling), the overall power consumption in this embodiment can be significantly reduced to 1/4.
此外,在本發明的實施例中,在DRX開啟期間,數據機處理器222可確定通信設備100是否仍需在後續DRX關閉期間醒來並執行RS測量的接收活動,並在確定通信設備100需要在後續DRX關閉期間醒來並執行RS測量的接收活動時,確定RS調度樣式。In addition, in an embodiment of the present invention, during DRX turning on, the
第7圖是根據本發明實施例的後續DRX關閉期間待調度的參考信號的接收視窗選擇的示範性示意圖。在本發明的實施例中,數據機處理器222可選擇待調度參考信號的接收視窗位於當前DRX關閉期間(如第一排所示的SSB的接收視窗,或第二排所示的TRS的接收視窗)、剛好在下一個DRX開啟期間之前(如第三排所示的SSB的接收視窗,其與下一個DRX開啟期間的前半部部分重疊),或者剛好在下一個DRX開啟期間之後(如第四排所示的TRS的接收視窗,其與下一個DRX開啟期間的後半部部分重疊)。在一些優選實施例中,RS接收視窗與DRX開啟期間至少部分重疊。Figure 7 is an exemplary schematic diagram of reception window selection of reference signals to be scheduled during subsequent DRX shutdown according to an embodiment of the present invention. In an embodiment of the present invention, the
